INJECTOR.

To all whom it may concern: I

Be it known that I, LnoroLD 'KAssANDnR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Injectors, of which the following is a specification.

This invention relates to injectors adapted to be used in feeding boilers and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

Locomotive construction has developed in such a direction that there has been a continual increase in the size of fire boxes and a continual reduction of the available-space between the side of the fire box and the side wall of the cab. Consequently, the space within the cab which formerly was ample for the installation of the auxiliary devices under control of the engine men has been lessened and, at the same time, the number and size of such devices has increased. The injector is one of the most essential of the auxiliary devices referred to. Heretofore it has been customary to locate the injector within or near the cab so that the engine driver might not only operate it but be able readily to observe its operation.

It is the purpose of this invention to provide means for operating and observing the performance of the injector when it is placed below and outside of the cab, and to arrange the devices embodying the inven tion so that the engine driver will be informed concerning the injector without any inconvenience.

The invention is shown as applied to a non-lifting injector, that is to an injector placed below the lowest level of the water in the supply tank, so that such water will flow into the injector by gravity and is not required to be lifted to obtain the supply to be forced into the boiler. The invention, however, is equally applicable to lifting injectors. I

In the drawings, Figure l is a general view of :the cab end of a locomotive and part of the running gear illustrating the location of an injector equipped with the invention. Fig. 2 is a side elevation and partial vertical section of a non-lifting injector.

Fig. 3 is a longitudinal vertical section of the injector taken at right angles to Fig. 2, and Fig. 4 is a transverse section.

In the drawings, 10 indicates the cab of a locomotive, and'll its running gear. The injector is secured in any suitable manner (preferably upon a bracket provided for the purpose) outside of and below the cab, at a level beneath the bottom of the water supply tank, which is of usual form and position and is not shown in the drawing. 12 is a pipe leading from such tank to the'inlet port 13 of the injector, which port is controlled by a valve 14 operated by a screw spindle 15 by means of a long rod 16 extending up into the cab 10 Within convenient reach of the engine driver and adapted to be rotated by a handle 17 20 is a pipe leading to the water chamber of the boiler, and 21 is a non-return valve governing the outlet from the injector into such pipe. 30 is apipe leading from the steam space of the boiler to the injector and the admission of steam therefrom is controlled by a valve 31 operated by a spindle 32 by means of a long rod 33 extending up into the cab 10, within convenient reach of the engine driver and adapted to be rotated by a handle 34. 40 is the casing or body of the overflow attachment the overflow chamber of which is controlled by a valve 41 operated by a spindle 42 by means of a long rod 43 extending up into the cab within convenient reach of the operator and adapted to be rotated by a handle 44. By this construction it is seen, the steam, water and overflow controlling devices are all located within the same zone at the cab and within easy reach of the hand of the engine driver.

The injector is provided with the usual nozzles, 50, 51, 52 and 53, of conventional construction. Its operation is well known. Water having been admitted through the port 13 and valve 14, the steam valve 31 is gradually opened and the water supply is regulated by the valve 14 until the injector' delivers water to the boiler with the overflow dry that is without any spilling of steam or water at the overflow. It sometimes happens however that the jet of feed water'will not be properly established or the injector will break or flyoif In such case the steam does not blow back into the tank but blows out through the overflow into the atmosphere. For such reason the described injector is said to be of the open overflow type. If the injector and its immediate connections are outside of the cab and not within the range of the operators vision, he may not know at once that the injector is not properly op erated and the immediate purpose of the invention is to provide means whereby he may be promptly notified of such conditions, and such means are provided by a simple addi tion to the overflow attachment.

60 is a hollow extension secured to or made integral with the casing 40 containing the overflow valve 41. Its interior communicates with the space beneath the valve 41 by means of a passageway 61, and with the space above the valve 41 by means of a passageway 62. It is provided with a hollow cap 63 to which there is connected a pipe 64 leading up to the cab in convenient proximity to the rod handles 17, 84- and 14, and within the range of vision of the engine operator and preferably terminates in a goose neck 65 provided with a nozzle 66. Within the extension 60, which is preferably made cylindrical there is arranged a reciprocating valve member 67 provided with external grooves or channels 68. Stop lugs 69 serve to limit the upward movement of the valve 67 so that an open space will always remain above the valve in com munication with the passageway 62. The valve 67 is made of such weight that it will not be opened by the force of water entering the injector when the overflow valve is closed. 1

Suppose that the injector is operated, as usual, with an open overflow and it does not start properly or breaks after starting. Then steam will pass into it and open the overflow valve 41. The greater portion of such steam will blow out into the atmosphere; but, a portion of it will pass through the passageway 62 into the extension 60, above the valve 67 and into the pipe 64 and out of the nozzle 66 where it will attract the attention of the operator and inform him that the injector is not operating properly. On the other hand, suppose that the injector is operated with a closed overflow. If it does not start or breaks, the overflow valve does not open. 'The valve 67 will be opened by the incoming steam which will pass along the grooves or channels 68 into the pipe 64 and out through the nozzle 66, and this will attract the attention of the operator and inform him that the injector is not operating properly. It will be seen therefore that by the use of the invention the operator will be informed that the injector is not working properly whether the overflow is open or closed.

It will be understood, of course, that the visible signal to the engine man formed by the escaping steam from the nozzle at the cab may be converted readily into an audible signal or some other form of visible signal in a manner known to the art and without departing from the principle of the invention.
